犬回结肠括约肌（ICS）处的张力和相位压力由结合套筒传感器和多个侧孔压力端口的测压组件记录。通过精确对准侧孔，可以在体内评估套管相对于来自点传感器的同时压力记录的保真度。ICS表现出强直性和相位性压力，通常超过100 cmH2O的压力。套管传感器可耐受组装件相对于ICS的微小但可能重要的移动。因此，记录点进出高压区和侧孔不是括约肌张力的理想传感器。该套管的预期特性，即在远离其灌注点的部位压力快速变化时显示降低的保真度，已在体内得到证实。套管还“总结”了相位爆发，无法监测此类事件的传播。然而，组合组件被证明非常适合检查犬ICS的整体功能。
Tonic and phasic pressures at the canine ileocolonic sphincter (ICS) were recorded by a manometric assembly that combined a sleeve sensor with multiple side-hole pressure ports. By aligning the side holes precisely it was possible to evaluate in vivo the fidelity of the sleeve relative to simultaneous pressure records from the point sensors. The ICS exhibited tonic and phasic pressures, often in excess of 100 cmH2O of pressure. The sleeve sensor was tolerant of small, but potentially important, movements of the assembly relative to the ICS. Point sites of recording moved in and out of the high-pressure zone and side holes were, therefore, not ideal sensors of sphincteric tone. The anticipated properties of this sleeve, that it would display reduced fidelity for rapid changes in pressure at sites away from its point of perfusion, were confirmed in vivo. The sleeve also “summarized” phasic bursts and was unable to monitor propagation of such events. However, the combined assembly proved excellent for examining overall function of the canine ICS.
